In a large mixing bowl, beat together butter and cream cheese until combined. Add sugar and beat until well mixed. Mix in egg and vanilla. Add flour mixture and beat just until combined.

Evenly divide the dough in half, wrap well in plastic wrap and refrigerate until firm, at least 2 hours.

Preheat oven to 375

Working with one piece of dough at a time, roll out the dough on a lightly floured surface to about 1/4" thickness. Using your desired cookie cutter, cut out as many shapes as possible. Repeat with remaining dough - re-roll scraps, if desired. We only re-rolled the scraps once. Place cut out dough onto parchment lined baking sheets and bake until edges are very lightly browned, about 7 to 10 minutes. Transfer the cookies to a wire rack to cool completely.

Makes several dozen depending on the size of your cookie cutter. Dip in chocolate, enjoy plain or pour over White Chocolate Fondant Icing for a fancy finish.
